187976-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187976-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187976-22:
(8*1)+(7*8)+(6*7)+(5*9)+(4*7)+(3*6)+(2*2)+(1*2)=203
203 % 10 = 3
So 187976-22-3 is a valid CAS Registry Number.
