77611-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77611-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,1 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77611-38:
(7*7)+(6*7)+(5*6)+(4*1)+(3*1)+(2*3)+(1*8)=142
142 % 10 = 2
