77570-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77570-24-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,7 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77570-24:
(7*7)+(6*7)+(5*5)+(4*7)+(3*0)+(2*2)+(1*4)=152
152 % 10 = 2
So 77570-24-2 is a valid CAS Registry Number.

Synthesis of Methylthio- and Aminoalkylidene Derivatives of Meldrum's Acid
Huang, Xiang,Chen, Bang-chi
, p. 480 - 481 (2007/10/02)
Reaction of Grignard reagents with isopropylidene bis(methylthio)methylenemalonate (1) resulted in conjugate addition to give an intermediate 2, which could either be hydrolyzed to an isopropylidene (1-methylthioalkylidene)malonate 3 or reacted with ammon
