Check Digit Verification of cas no
The CAS Registry Mumber 7783-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7783-33:
(6*7)+(5*7)+(4*8)+(3*3)+(2*3)+(1*3)=127
127 % 10 = 7
So 7783-33-7 is a valid CAS Registry Number.
